The moon’s surface is covered by ancient lava flows that are often different from those found on the earth. While volcanic rocks on the earth rarely contain more than 2% titanium dioxide (TiO2), some lunar basalts — common volcanic rocks — carry up to 18%, a fact that planetary scientists have struggled to explain for … Read more
For more than a century, physicists have looked for a material that conducts electricity with zero resistance at room temperature — practical enough to transform how the world generates and uses energy. But for a long time, the highest temperature at which a material became superconducting at room pressure was -140 °C. Some other materials … Read more
On March 10, a journal called Science of Climate Change published a paper calling into question the foundations of climate change. The paper concluded that after accounting for some sources of uncertainty in the climate data, the ‘correct’ changes in the oceans’ heat content and Earth’s energy imbalance are practically zero. In other words, the … Read more

From African deserts to the Arctic circle: humans spread across the planet faster and farther than any other wild vertebrate, making us outliers in the animal kingdom. While we occupy 132 million sq. km of land, a typical wild mammal occupies 165 sq. km. How did humans achieve this feat? The answer lies in … Read more
In the 2026-27 budget, the outlay for the PM-KUSUM scheme nearly doubled to Rs 5,000 crore, signalling the government’s renewed emphasis on increasing solar power production centred on India’s farmers. Specifically, the scheme aims to provide energy and water security to farmers, enhance incomes, and decarbonise the farm sector through decentralised solar pumps and power … Read more
